APPARATUS FOR ROLLING TIN PLATES.

- Specification of Letters Patent. Patented Sept. 28, 1909. Application filed August 28, 1902. Serial No.

a) all whom it may concern:

Be it known that 1, CHARLES \V. BRAY, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Apparatus tor-Rolling Tin-Plate, of which the following is a full, clear, and exact description, reference being had tothe accompanying drawings, forming part of this specification,

I t consists in providing for this purpose a continuous roughing mill for rolling the bars to passing them through the finishing mill, and interposing between two of the stands of roughing rolls a doubler by doubled on its way It also consists in the apparatus above mentioned when combined with a second 4 doubler set at the delivery end of the roughmg mill so that the metal is first doubled during its passage through the continuous roughing mill, and is again doubled afterit has left the last pass of-said mill.

By use of this mechanism I put the metal in the best form for handling in the rolls, holding it together securely, and obtain thereby improved results.

-Thc apparatus is made to enter the doubled piece automatically into the rollswith the doubled end foremost, and all tendency of the rolls to patch or buckle the end of the sheets is prevented.

In the drawings, 2, 3, 4, 5, 6, 7, 8 and 9 are sets of rolls of a continuous roughing mill, through which the bar is passed after it. has been taken from the heating furnace. Bet-ween two of these sets of rolls, preferably between the rolls 7 and 8, I place a doubler B which may consist of two sets of rolls 10 'and 11 set with their passes in the same vertical plane above a convevmg table 12 which extends between the sets of rolls 7 directly below these passes is a moving pusher 13. through the rolls 7 table 12, it is arrested by a stop .14 on said table so that its middle will be directly above the pusher, and the pusher is then raised so as to crease. the metal at the middle and to enter it between the rolls'lO. It is carried up between the rolls'lO and 11, and is douand 8, and

vertically After the bar has )assed and is delivered upon the bled thereby and is delivered upon the table in front. of the rolls 8 with its doubled end foremost by guides 15 and 16 which constitute the delivery portion of the doubler. It then passes through the rolls 8 and 9 with the doubled end still foremost to a. table 17, on which itis arrested by a' stop 18, and it. is again doubled by a doubler C which may be similar in construction to the doubler B. The doubled metal sheet is then taken to the finishing rolls where it .may be rolled in the usual manner.

The construction and arrangement of the parts may be varied by the skilled mechanic within the scope of my invention, since lVhat I claim is:

1. A roughing mill having a doubler located between two sets of its roughing rolls, there being a continuous path of feed for all of the rolls, the pusher ot' the doubler working across said path of feed, substantially as described.

' '2. A roughing millcomprising a continuous train made up of several sets of rough ing rolls, there being a continuous path of feed for all of the rolls, two adjacent sets of rolls being separated by an abnormal space, a doubler located in said space and having a pusher Workingacross said path of feed, a feed table leading from the preceding set of rolls to the doubler, and another teed table leading from the doubler to the succeeding set of rolls, substantially as described.

- In testimony whereof, I havehcreunto set my hand.
